Elastomers we offer
As the name would indicate, this elastomer occurs naturally and comes from the latex of certain trees and plants. After the latex is processed, it becomes an elastomer with excellent mechanical properties. It has excellent tensile, elongation, tear resistance and resilience. It has good
abrasion resistance and excellent low temperature flexibility. Without special additives, it has poor resistance to ozone, oxygen, sunlight and heat. It has poor resistance to solvents and petroleum products. Useful temperature range is -67° F to +180° F (-55° C to +82° C).
Fluoroelastomers or Fluorocarbons (FKM), also known as Viton®, are highly fluorinated polymers that are suitable for continuous use at elevated temperatures. Various grades are available, including copolymer and terpolymers. The most common grades consist of tetrafluoroethylene,
hexafluoropropylene, and vinylidene fluoride. Fluoroelastomer compounds are widely used in the chemical, automotive, aerospace, and energy industry. They are used for hoses, diaphragms, accumulator bladders, gaskets, O-rings & seals, all operating in especially harsh environments.The typical service temperature of FKMs is between -20°C (-5°F) and +230°C (+445°F). They can, however, withstand temperatures up to 300°C for a short period of time. However, at high service temperatures FKMs are weak, so that the design must prevent any high loads.
